Q: What's the difference between fiberglass insulation and foam board?

• <div><p>When it comes to <a href="https://www.angi.com/articles/fiberglass-insulation-vs-foam-board.htm">fiberglass insulation versus foam board</a>, there are a few notable differences, both aesthetically and functionally. Fiberglass insulation is soft and flexible, meaning it can be squeezed into tight spaces more easily than foam board. Fiberglass insulation also has a higher R-value, making it a better pick for colder climates. However, foam board insulation can resist moisture and pest damage much better than fiberglass. </p></div>

Q: Does tin foil on windows help with heat?

• <div><p>Spreading tin foil over your windows works similarly to <a href="https://www.angi.com/articles/radiant-barrier-cost.htm">radiant barrier insulation</a>, but not as well. It will reflect some of the sunlight that would otherwise come through the glass and warm up the inside of your home, so it might help a little to keep your home cool in the summer. However, the appearance isn&rsquo;t preferable to blinds or drapes that can offer the same benefits. You might also consider tinting your windows instead, which is a more aesthetically pleasing change that can still block a good portion of the solar heat coming through your windows.</p></div>

Q: Why should attic insulation installation be done professionally?

• <div><p>Ensures uniform application and maximizes insulation effectiveness and energy savings.</p></div>

Q: What happens if you don't install a vapor barrier?

• <div><p>While not every wall requires a vapor barrier, if you do need one and don&rsquo;t install it, moisture can get between the walls of your home. This can lead to water damage from mold growth or rot, and the excess moisture could also attract pests, including termites, cockroaches, or ants.</p></div>

Ensures uniform application and maximizes insulation effectiveness and energy savings.

Ideally, you can add new insulation to your existing insulation. However, some circumstances require you to remove old insulation before adding any new insulation:

If the insulation is over 15 years old
If the insulation is wet or moldy
If it is vermiculite insulation
If you see signs of pest infestation

Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.

While not every wall requires a vapor barrier, if you do need one and don’t install it, moisture can get between the walls of your home. This can lead to water damage from mold growth or rot, and the excess moisture could also attract pests, including termites, cockroaches, or ants.
